Macklemore may be all for ‘Same Love’ but it looks like he’s still got a lot to learn when it comes to respecting people who are different from him. The rapper is in hot water after he donned a costume resembling a collection of offensive Jewish stereotypes at a concert in Seattle on May 16.

Fans who stopped by Seattle’s EMP Museum for the opening of a new exhibit on May 16 got to see a surprise performance from award-winning artists Macklemoreand Ryan Lewis. The crowd seemed to enjoy the show at the time, but once photos from that night of Macklemore in a dark wig, beard and oversized prosthetic nose started surfacing online, fans quickly grew furious over what they saw as an offensive, anti-Semitic costume. Macklemore has since denied that his concert costume was a Jewish stereotype, but critics — including Seth Rogen — remain skeptical.

Macklemore’s costume, which was described by the Daily Dot as “some kind of Jewish caricature, prosthetic schnozz included,” is stirring up a lot of controversy on Twitter.

Fans seem to feel that the rapper was undeniably mocking Jewish stereotypes with his wig, fake beard and prosthetic nose, and it’s hard to argue with them.

Macklemore, who is not Jewish, didn’t even bother to explain the meaning behind his costume during his performance, which was part of the opening of a new exhibit at Seattle’s EMP Museum called “Spectacle: The Music Video.”

Now the rapper has a lot of angry fans on his hands — some of them famous.
